Just a simple trick that is often used. You’re working in mc and need to issue a command from the command line. You can “minimize” Midnight Commander window and then return back to the place you were before with just a simple keyboard shortcut. Just input Ctrl+O to hide mc window. Command line interface will appear with the path being the same as it was in active Midnight Commander window. In order to return back to mc, just press Ctrl+O once more and you will return to its interface.
This option is not documented well; I never seen this info that’s why I’d like to share it with you. Happy mc usage! :)
